New progress in the anti-static technology of polyester hot-melt wire: innovation and breakthrough
In the textile field, polyester hot-melt wire is widely used due to its unique properties, but the anti-static problem has always been the focus of research. In recent years, polyester hot-melt wire anti-static technology has made many progresses, which are introduced in detail below.

I. Application of new anti-static agents
(I) Nanomaterial anti-static agents
Nanomaterial anti-static agents such as nanographene and zinc oxide have become a research hotspot. Nanographene has excellent electrical properties and can effectively improve the conductivity of polyester hot-melt wire, thereby enhancing the anti-static effect. Its two-dimensional honeycomb lattice structure enables it to form a good conductive network on the fiber surface, reducing static electricity accumulation. Zinc oxide forms additional energy levels through its own defects, promotes the improvement of conductivity, and synergizes with nanographene to further optimize the anti-static performance.
(II) Improvement of silicone antistatic agents
Traditional silicone antistatic agents are highly dependent on environmental humidity. When the humidity is high, the conductivity is enhanced after absorbing moisture, and the effect is poor when the humidity is low. The newly developed silicone antistatic agent reduces the effect of humidity on antistatic performance by optimizing the molecular structure and adding special additives. Under different humidity environments, it can maintain good conductivity and stability, making the antistatic performance of polyester hot melt more reliable.

2. Fiber modification technology
(I) Blending modification
Blending conductive fiber with polyester hot melt is an effective way to improve antistatic performance. For example, stainless steel fiber or carbon fiber is mixed with polyester hot melt, and the conductive fiber forms a conductive channel in the polyester hot melt to promote static discharge. By adjusting the content and distribution of conductive fiber, different antistatic grade requirements can be met.
(II) Surface modification
The use of surface modification technologies such as plasma treatment and chemical plating can also significantly improve the antistatic performance of polyester hot melt. Plasma treatment can produce hydrophilic groups on the surface of polyester hot melt, increase hygroscopicity and improve conductivity. Chemical plating deposits a layer of metal or alloy on the fiber surface to form a conductive layer, which effectively prevents static electricity accumulation.

3. Production process optimization
(I) Adjustment of spinning process
During the spinning process, the internal structure and surface properties of polyester hot melt yarn can be improved by adjusting parameters such as temperature, humidity, and speed. Appropriately increase the spinning temperature to make the polymer molecular chain more regular and reduce the generation of static electricity; control the spinning speed to avoid static electricity caused by excessive speed causing increased friction on the fiber surface.
(II) Improvement of post-processing process
The post-processing process also has an important influence on the anti-static performance of polyester hot melt yarn. The use of appropriate heat setting, oiling and other processes can improve the crystallinity and surface smoothness of the fiber. Heat setting stabilizes the fiber structure and reduces the generation of static electricity; oiling forms a protective layer on the fiber surface, reduces the friction coefficient, and prevents static electricity accumulation.

4. Intelligent monitoring and control
(I) Static electricity monitoring system
With the development of science and technology, intelligent static electricity monitoring systems have been applied in the production of polyester hot melt yarn. The system can monitor the static electricity situation in the production process in real time, collect static electricity data through sensors, and transmit it to the control center. Once the static value exceeds the set threshold, the system automatically alarms and takes corresponding measures, such as adjusting process parameters, starting static elimination devices, etc., to ensure production safety.
(II) Static elimination equipment
New static elimination equipment continues to emerge, such as ion blowers, static elimination rods, etc. These devices neutralize the static charge on the surface of polyester hot melt yarn by generating a large number of positive and negative ions to achieve the purpose of eliminating static electricity. Ion blowers can be installed above production equipment to continuously release ions and eliminate static electricity; static elimination rods can directly contact fibers to quickly neutralize static electricity.

V. Green environmental protection and sustainable development
(I) Environmentally friendly antistatic agents
The research and development of environmentally friendly antistatic agents has become an important trend. Traditional antistatic agents may contain heavy metals or other harmful substances, which are harmful to the environment and human health. New environmentally friendly antistatic agents use natural plant extracts, bio-based materials, etc. as raw materials, and have the advantages of being non-toxic, pollution-free, and degradable. For example, using plant cellulose as a reinforcing agent not only improves the antistatic performance of polyester hot melt yarn, but also enhances its environmental friendliness.
(II) Recyclable technology
The recycling technology of polyester hot melt yarn has also made progress. Through chemical recycling and physical recycling methods, waste polyester hot melt yarn can be converted into recycled raw materials and reused in production. This not only reduces resource waste and environmental pollution, but also improves the economic and social benefits of enterprises.
In summary, the anti-static technology of polyester hot melt yarn has made significant progress in new anti-static agents, fiber modification, production process optimization, intelligent monitoring and control, and green environmental protection. These innovations and breakthroughs provide strong support for the application and development of polyester hot melt yarn, making it more competitive and market-oriented in the textile field. In the future, with the continuous advancement of science and technology, the anti-static technology of polyester hot melt yarn will continue to improve and innovate, and make greater contributions to the development of the textile industry.
